Today Nokia andQt released the Beta version of Qt 4.6.0. Qt is a cross-platform application and UI framework. Using Qt, one can write applications once and deploy them across desktop, mobile and embedded operating systems without rewriting the source code. The beta runs on S60 3rd Edition as well as 5th Edition devices. I’ve installed it on my Nokia N97 and it looks really impressive. The focus of this release has been to stabilize the Symbian port, as well as adding a backend for the Phonon multimedia library enabling simple audio and video playback. The “Colossus” beta-release contains QtCore, QtTest, QtGui, QtNetwork, QtScript, QtSvg, QtWebKit, QtXML and Phonon as well as documentation and examples and demo.

To download Colossus straight to your phone point your phone’s browser to qt.nokia.com/phonedemo. For best performance we recommend to install in Phone memory.
